HEAVILY LOADED FLAME RETARDANT URETHANE AND METHOD Abstract of the Disclosure The invention disclosed relates to a new polyurethane composition having improved flame retardance and to a method for preparing same. The present composition is prepared by using a suspending agent and a surfactant. The suspending agent may be either a surfactant or an appropriate polymer, but to control the cellular structure, a surfactant that does not perform as a suspending agent is desirable. The resultant composition may be sprayed through a high pressure spray gun while permitting forma- tion of heavily loaded flame retardant urethane foams which are neither dusty nor lose solids upon washing. - 1 -
